Spirulina is the food with the highest biological value of plant protein in nature, although it looks like a simple alga. It contains 65% protein, which is about 2 times more than its closest competitor, the soybean. Spirulina, which has the highest organic iron content in the world, contains 58 times more iron than spinach and 28 times more than beef liver. It is the plant that contains the most vitamin B-12 in nature. It contains 2-6 times more vitamin B-12 than calf's liver. Also rich in antioxidants, Spurilina contains minerals such as zinc, magnesium and copper, the amino acids methionine and beta-carotene, vitamin E, vitamins B-1, B-5 and B-6, and selenium.
Spirulina cultivation only thrives in alkaline lakes with a high pH and in large outdoor ponds under controlled conditions. The climatic conditions in Greece, Japan, India, the USA and Spain are ideal for the production of this algae. Quality spirulina is also characterized by a particularly dark green and natural colour.
